Truly don't think it's half. It's just the way our elections and voting works. Every the stupid minority has a loud voice when we weigh votes instead of simply going for popular votes overall.
You need to factor effects from gerrymandering and other forms of vote suppression. I think there’s a lot of wealth trapped in the hands of a few very shitty people, which has allowed them to shape / distort perceptions of just how “popular” their values really are.
